DNS Record Types

A records map a domain name to an IPv4 address. AAAA records map a domain name to an IPv6 address. MX records route email to a mail server. NS records delegate a domain to a name server. SOA records store information about a domain's name servers and are used to verify domain ownership. The DNS record types can be broadly categorized into two main groups: resource records (RRs) and pseudo-RRs, each playing a vital role in the functioning of the DNS. RRs are used to store information about a domain, such as its IP address or mail server. Pseudo-RRs are used to store information about the DNS itself, such as the location of a domain's name servers.
